Emission of electromagnetic cascades due to photons of energies >3 GeV from 300-GeV proton-nucleus collisions has been studied in emulsion. The curious ''delayed-cascading'' effect is evidently much enhanced at larger emission angles, >25 mrad. Samples of 384 ''normal'' cascades and 642 ''slow'' cascades have therefore been extracted from among those cascades of long (>20 mm) rectilinear path length. The angular distribution shown by the slow cascades is different from that for the normal cascades, lending support to the suggestion that two kinds of photons might convert to primary pairs in the experiment.
